A possible related issue (or not)
(in unicode flavour) and normal spaces are not distinguished in the autocompletion dropdown menu in the Find/Search text box.
I mean, in the book I'm reading (Infinite Jest) there are some possessive "’s" for "commented" texts. Let's say "‘Cheers!’ ’s". And I've wanted to change that space in the middle by a
(in unicode flavour). But while typing "’
’" (through copy/paste, and the GOOD copy/paste through keyboard shortcuts

), the dropdown menu has offered my previous typed "’ ’" with just a normal space. Is this to be expected? Can it be filtered?
And another small possible enhancement. Would it be possible to translate the colours used in the editor to that dropdown previous searched/replaced string matches? I mean there's no way to tell the difference between space types in that dropdown lists.
